Termografía de infrarrojos aplicada a la conservación del patrimonio cultural

Zusammenfassung

The infrared thermography (IRT) applied to the cultural heritage is a non destructive diagnostic and inspection tool without physical contact which is based on the analysis of thethermal behavior of materials and their relation with the material properties and structural characteristicsthat are used to watch the deterioration processes of the cultural heritage. Application and adjustment of this analytical technique is one of the works development by thePreventive Conservation Section in the Research and Formation Departament of the Spanish Cultural Heritage Institute. The infrared thermography is used by technical personnel of the Section since 1989 to investigate structures, cracks, hollows and to identify secret elements and dampness in heritage buildings. It is in dampness diagnosis with IRT in which the Preventive Conservation Section is taking an extraordinary impulse thanks to a research project called “Studies for diagnosis and control of damp, in a preventive conservation view, in buildings declared BIC (Important Cultural Heritage)», awarded to the company Water Wood, S. L. from March 2011 to March 2013. This study are carried out some very important works in the cloister of the monastery of Santo Domingo de Silos (Burgos), in the wall paintings of the hermitage of San Antonio de la Florida in Madrid, in the wall paintings of the «Regina Martyrum» dome in the basilica of Nuestra Señora del Pilar in Zaragoza, in the «Cielo de Salamanca» of the museum of the University of Salamanca, in the hermitage of Santo Cristo de la Luz in Toledo, in the hermitage of San Baudelio de Berlanga in Casillas de Berlanga (Soria), and some many more. This article shows the experience learned and development by the authors in the use of the infrared thermography for detecting moisture or other different pathologies linked with heritage buildings.
